Federation is a fresh idea in the social media realm. Not chronologically, obviously (sorry mastodon), but fresh in the sense that it has buzz and momentum now that it hasn’t really had before as a direct result of the “staleness” associated with data collection, advertising, and corporate greed by the big players. There are no fresh ideas from meta, Twitter, and tiktok because their goals are stale. Bluesky is very buzzworthy, and if they can build out and scale up fast enough they have a chance.
